数组运用技巧

$a = Array
 (
     [0] => Array
         (
             [date] => 2019-12-02
             [time] => 1575216000
             [week] => 周一
         )    [1] => Array
         (
             [date] => 2019-12-03
             [time] => 1575302400
             [week] => 周二
         )    [2] => Array
         (
             [date] => 2019-12-04
             [time] => 1575388800
             [week] => 周三
         )    [3] => Array
         (
             [date] => 2019-12-05
             [time] => 1575475200
             [week] => 周四
         )    [4] => Array
         (
             [date] => 2019-12-06
             [time] => 1575561600
             [week] => 周五
         )    [5] => Array
         (
             [date] => 2019-12-07
             [time] => 1575648000
             [week] => 周六
         )    [6] => Array
         (
             [date] => 2019-12-08
             [time] => 1575734400
             [week] => 周日
         ))
 $b = Array
 (
     [0] => 公司
     [1] => 公司
     [2] => 公司
     [3] => 公司
     [4] => 公司
     [5] => 公司
     [6] => 休息
 )需要将数组b的值拼接到数组a对应的Key的值
 foreach($a as $key=>$val) {
        foreach($b as $k=>$value){
             $a[$k]['content'] = $value;
        }  
    }//拼接后的结果
